Voldicon voltage digitizers - Adage:

A complete 14-bit A-to-D conversion in under 4 /isec...
that’s something to write about!

We’re delighted with the over¬
whelming number of inquiries
we’ve received about our two
new additions to the Adage
VOLDICON"" line of voltage
digitizers.

The high-speed, high-resolu¬
tion VT13-AB and ultra high¬
speed VT7-AB are based on a
novel design combining tech¬
niques of successive approxi¬
mation and parallel threshold
decoding. The VT13-AB ac¬

complishes a 14-bit analog-to-
digital conversion in less than
4 microseconds. The 8-bit
VT7-AB performs a complete
conversion in under 800 nano¬
seconds.

A full line of data systems
components, including other
A-to-D converters, D-to-A con¬
verters, multiplexers, opera¬
tional amplifiers, and digital
logic, is available from Adage,
Inc. These components use

all-soiid-state circuitry and
are designed and tested to
m^et the most demanding re¬
quirements for accuracy and
reliability.

Why not add your inquiry to
the many we’ve already re¬
ceived? We would be pleased
to send you a technical bro¬
chure on the VT13-AB and
VT7-AB. Call or write I. R.

ADAGE ANNOUNCES NEW HYBRID MULTIPLIER
— Important Advantages for Hybrid Simxxlation,

Data Acquisition, and Display Generation

Adage, Inc. announces a new "Y"-series of Hybrid Multiplying Elements
that greatly simplify data handling in systems using both analog and digital signals.
These HME's accept an analog and a digital input, multiply the analog value by the
digital, and output the product in analog form.

The HME replaces mechanical potentiometers, substituting digitally-controlled
electronic potentiometers. It thus eliminates all moving parts and speeds up problem

solving by slashing pot-setting times — the HME settles to 0. 01% of final value
in less than 50 microseconds for a step change of 200 volts. The HME's 15-bit
resolution also exceeds that of any motor-driven potentiometer.

Adage HME's also eliminate much signal conversion and reconversion.
Previously, all arithmetic operations were performed in either the analog or
digital domain. Now, however, when an analog signal is to be multiplied by a
value that has been calculated digitally, the two signals can be fed to a hybrid
multiplying element, which then directs its analog product back to the analog com¬
puter.

Hybrid multiplying elements at the front end of a data acquisition system
allow scaling and a quick look before A-to-D conversion of data. They also ease
the task of function generation and display of data.

These elements in the Y Series are available with 12- or 15-bit resolution,
buffered or double-buffered, and with outputs to ±100 volts. Wide-band noise is less
than 2 millivolts rms over a lOOkhz bandwidth. Use of integrated circuits allows
greater packing densities and lower prices. Eor example, eight multiplying elements
can be housed in a single 5-1/4-inch-high case which mounts in a standard 19-inch
rack. Prices start at $930.
